EIA has expanded Sections 1 through 10 and Appendix A of the Monthly Energy Review (MER) to incorporate annual data as far back as 1949 in those data tables that are published in both the Annual Energy Review 2011 and MER. Similar revisions are pending for Section 12.

Where available, Excel and CSV files now include pre-1973 data. For tables containing monthly and annual data, the Excel files now have two worksheets, one for monthly data and one for annual data.

The Monthly Energy Review now includes interactive data tables and graphs. The interactive tables are currently on EIA's Beta site.
